CLOSURE FOR PEEPHOLES AND'TI-IE LIKE.

Application filed May 12,

This invention relates to peep holesand thelike and to improved closures therefor and ineans'for operating them. My invention has many applications among which may be mentioned doors in apartment houses, lodges; also, enclosures where certain precautions are taken for guarding lives and property, etc. i g g I A principal object of my invention to provide means for raising and lowering the gate for the peep hole. I

Another principal object is to provide mechanism adapted to r adily raise or lower the gate from the inner side of the inclosure, and to anchor the gate against movement by any attempt to raise or lower the same from a position exterior of theinclosure.

Another object of my invention is to provide means for safe-guarding persons or property within the inclosure from exterior attacks through the peep holes by provldmg means for closing the gate and automatically locking the same in closed position against any attempt from the exterior-to open the same. 7

It is a further object to provide a device of this character in which the shutter may be maintained in any adjusted position.

Other objects will be apparent from reading this specification in connection with the accompanying drawings in which,

Figure l is an elevation view of my device looking at the inner side thereof, in which the gate is in closed position;

Figure 2 is a, vertical cross section taken along the line 22 of Figure 1;

Figure 3 is an elevation of mydevice looking at the inner side thereof in which the gate is shown in raised position, the peep holes being uncovered for service; and

Figure 4 is a horizontal cross section taken along the line 4-4 of Figure 3.

Referring now in detail to the drawings in which similar reference characters refer to similar parts throughout: 5 represents one of the sides of an inclosure in which is mounted the peep hole plate 6 provided with the peep holes 20, 20. The plate 1sprovided with vertical guides 7, one at each side thereof, between which is adapted to slide the gate 8 in an upward and downward direction in the embodiment shown in the drawings, purposes of these guides being to restrict lateral movement of the gate and to maintain it in adjusted position and to add strength to the peep hole plate 6.

1327. {Serial No. 190,7133. V

Adjacent to theinner surfaceof the gate {dis a carrier 9 provided. with the project-- mg arms 1()11 in slidahlerelation with the saddles 12. and 13 respectively, which sad dles are secured to the peep hole plate 6 by the screws Orcther fastenings 14;, and which also secure .the carrier to the plate Mounted on the gate ,8 are dete'nts ,or dogs 15 which are swivelly connectedtheretohy the pins'lii. Integrally mounted in the dogs 15 are pins 18 which project i n to theislots 17 of the carrier and operate in slidable relation therewith. r V g f Gate 8 also hasa vertically extending portion and a depending portion 26, the lat-- ter serving the purpose of affording means for holding the dogs '15 out of engagement withthe guides 7', as by the operator holding down the said portion 26 while pressing upwardly on handle 19 of the carrier 9. In

other words, by means of depending portion of the hand, it is attempted toraise the said gate by direct manipulation of the gate itself.

upon any vertical shift thereof, the pins 17 will in cooperation with their respective slots, swing the dogs outwardly against the guides 7, and further movement of the gate will anchorthe ends of the dogs into said guides, and thus hold the gate against further movement. In themanipulation of the carrier in a downward direction, the pins 18 will ride in the slots at their outer ends andmaintain the dogs 15 out of engaging contact with theguides 7. Furthermore, by means of the dogs 15 the gate 8 may be maintained in any raised position.

I have described what I believe to be the best embodiment of my invention. I do not wish to belimited in patent protection to the embodiment shown, however, but what I desire to cover by Letters Patent is set forth in the appended claims.

- I claim:' l

1. In combination with a peep hole structure, a .slidable gate adapted to cover and clear the peep hole opening, guides for said gate, detents swivelly mounted on said gate, a carrier, pins mounted in said detents, said pins being adapted to operate in slots in said carrier and withdraw the ends of said detents from contact with said guides upon direct operation of said carrier and to bind in said guides upon indirect operation of said carrier. V

2. In combination with a peep hole structure, aslidable gate adapted to cover and clear the peep hole opening, guides adapted to maintain the gate'in' alignment, a carrier loosely connected to and adapted to operate said gate, and means for maintaining said carrier in ope 'ative. connection With said gate. V

, 3. In combination with a peep hole structure,a slidable gate adapted to cover and operate the same, means for maintaining said carrier in connection with said gate,

and means for anchoring said When operated by said carrier.

4. In combination With a peep hole structure, a slidabie' gate adapted to cover and clear the peep hole opening, a carrier adapted to operate said gate, said carrier being loosely connected to said gate and secured in slidable relation to said peep hole'structure, detents carried by said gate adapted to gate, except anchor the gate against operation, except through said carrier.

In testimony whereof I have aflixed my signature to this. specification.
